There are several things that God is said to remember.
1. He remembers His people (Isa 44:21; Isa 49:15).
2. He remembers we are dust (Psa 103:14).
3. He remembers the sparrows (Luk 12:6).
4. He remembers deeds of kindness (Jer 2:2).
5. He remembers our works (Amo 8:7).
6. He remembers His mercy and truth (Psa 98:3).
7. He remembers His holy promise (Psa 105:42).
8. He remembers His covenant (Lev 26:42, 45; Deu 4:31; Eze 16:60; Psa 105:8; Psa 106:45).
Being God, He cannot forget, but knowing our frailty, He graciously speaks after the manner of men for our comfort and consolation.
